Startup Of The Week : Floatech

This week, we’re proud to feature Floatech, a deep-tech startup revolutionizing the battery industry with next-generation silicon anodes. Their innovative approach is helping unlock higher energy density and longer battery life — key to powering the future of electric mobility and renewable energy storage.

1. Tell us about your company. 

At Floatech, we are developing high-performance silicon anodes for lithium-ion batteries using a proprietary electrochemical process. Our technology overcomes the traditional limitations of silicon — such as volume expansion and instability — by creating a nanostructured, porous architecture that enhances both performance and durability. Based in Madrid/Spain, Floatech is working with battery manufacturers and research institutions to bring this breakthrough to market.

Floatech is currently raising a €10 million Series A round and is actively seeking a lead investor. The round is already 50% committed, backed by existing investors and public funding, making this a compelling opportunity to join a high-impact energy innovation venture. 

2. What made you become an entrepreneur? 

We saw a critical gap between academic research and industrial application in battery materials. Becoming entrepreneurs allowed us to bridge that gap and bring real innovation to a market that urgently needs it. We wanted to turn scientific insight into scalable, impactful technology.

3. What is the most challenging part of running your own startup? 

Managing uncertainty while staying focused on long-term goals. From technical hurdles in R&D to navigating supply chain issues and regulatory requirements, every day brings new challenges. But that’s also what makes the journey exciting.

4. What is the biggest challenge you have faced when looking for funding? 

Educating investors about the complexity and potential of battery materials. Many are familiar with EVs and energy storage, but fewer understand the critical role of anode chemistry. We’ve had to work hard to communicate both the technical depth and the commercial opportunity of our solution.

5. What is the most rewarding aspect of entrepreneurship? 

Seeing our technology evolve from lab-scale experiments to real-world prototypes. It’s incredibly rewarding to know that our work could help power the next generation of clean energy systems — and that we’re building something that truly matters.
